“…The positive correlation between the guesser's winning rate and significantly increased IBS was only in CFM dyads at CH03 (r = 0.59, p = Next, we sought to determine whether the increased IBS was modulated by relationship type and gender composition. The results of ANOVAs showed a main effect of relationship type in a large number of channels (i.e., CHs 1,5,6,7,9,10,11,12,14,16,17,18 at 0.086-0.192 Hz; CHs 2, 5, 6, 7, 9, 12, 14, 15, 17, 18, 19 at 0.011-0.022 Hz, all FDR-corrected) (see Table S5 in Supplementary Materials). The results also revealed that couple dyads showed more increased IBS than stranger dyads in all significant CHs.…”
